AI Technical Summary

Technical Problem

In the current technology for mass production of workpieces, deviations occur during the chamfering process of the gear system, causing some workpieces to exceed the tolerance zone and making it impossible to adjust automatically, thus affecting the machining accuracy.

Method used

By employing automatic detection of workpiece characteristic changes and adaptive adjustment of the tooth forming process during the second machining operation, including automatic adjustment of clamping height, tool position, and machine axis settings, the chamfering process is ensured to meet predetermined targets.

Benefits of technology

It reduces the relative deviation between workpieces, improves the machining accuracy and consistency of the gear system, and reduces the proportion of workpieces that exceed the tolerance zone.

Abstract

The present invention relates to a method for machining a tooth system, wherein, for a series of workpieces having the same target geometry, a tooth system is produced or machined on the respective workpieces in a first machining operation, and in a second machining operation, additional tooth forming of the tooth system produced by the first machining is performed by a machining tool in a relative positioning with respect to it, specifically chamfering of the tooth tip edges of the tooth system, wherein a controller of the second machining operation at least partially automatically detects changes in workpiece characteristics and / or settings of the first machining operation, specifically independent of the first machining operation, relative to a corresponding predetermined reference, and performs the relative positioning according to the detected changes.
